Understanding the server name alias and host name for an upgrade
During the installation on Windows or UNIX, you are asked for the BMC Remedy AR System server alias and a BMC Remedy AR System server host name or IP address, which is the physical system on which the BMC Remedy AR System server will be installed. (Because there are multiple aliases for each system, the host name might not match the server alias.)
When you install BMC Remedy AR System, the computer from which you are installing must be able to connect ("ping") to the server alias you provide. In the installer's AR System Server Name Alias field, enter the server's short name (for example, enter alpha instead of alpha.remedy.com). Additionally, make sure to configure the primary DNS suffix. For more information, ask your system administrator.
If the server will be accessible over a network, the server alias must be resolvable to an IP address. To make sure that clients can resolve the server alias:
- Use only alphanumeric names containing only lowercase letters a through z and numbers 0 through 9.
- You can use hyphens (-), but the name cannot start or end with a hyphen.
- Avoid underscores (_) and other special characters (for example, $) because these characters do not comply with DNS rules.
If you are installing multiple BMC Remedy AR System servers on a single computer, make sure each server alias is unique. To make sure that BMC Remedy AR System server aliases are unique, verify the following:
- The correct licenses are used.
- The correct BMC Remedy AR System database is used for each BMC Remedy AR System server.
- You can selectively stop and start server processes.
The BMC Remedy AR System server alias identifies the configuration file and the service (
armonitor) associated with each BMC Remedy AR System server.
On UNIX, the following daemons are listed for each BMC Remedy AR System server that is running:
arserverd. To display all services that are currently running, issue the following command:
# ps -ef | egrep ar
